 ## Technische notities
 
-- De Atom S3R Voice gebruikt de ES8311 audio codec op G45/G0/G48/G4/G3/G17/G11, IR TX op G47, en de knop op G41. Deze pinnen zijn niet beschikbaar voor eigen gebruik (behalve G41 als input).
+- De Atom S3 Lite heeft GPIO G1, G2, G5-G8, G38, G39 beschikbaar op de headers. G41 is de interne knop (active low). G46 is de interne LED.
 - G1 en G2 zitten op de HY2.0-4P Grove poort. G5-G8, G38, G39 zitten op de onderste expansie-header.
 - De firmware gebruikt geen M5Unified library — alleen Arduino core + ESP32 NimBLE + mbedtls.
 - `ARDUINO_USB_CDC_ON_BOOT=1` is ingeschakeld voor virtuele serial via USB.

+# HS-S43A Touch Migration + S3R Cleanup Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Remove internal pullups for HS-S43A touch sensors (invert logic), and purge all obsolete "Atom S3R Voice" references from code and docs.
+
+**Architecture:** Two firmware files get identical pinMode+logic changes. Six documentation/config files get S3R→S3 Lite corrections. Compile verification via `pio run` for both environments.
+
+**Tech Stack:** C++/Arduino, PlatformIO, Markdown docs, Bash scripts, YAML CI
+

+# Design: Touch sensor HS-S43A migratie + S3R referenties opruimen
+
+> **Issue:** [#5](https://git.eddydevink.nl/eddy/Project_SylDa/issues/5) — Verwijder internal pullups voor touch sensors
+> **Datum:** 2026-08-01
+
+## Aanleiding
+
+De touch sensoren zijn vervangen van JR223B (open collector/drain, heeft pullup nodig) naar **HS-S43A** (digitale output 0/1, actief = HIGH, geen pullup). Daarnaast bevat de documentatie verouderde verwijzingen naar "Atom S3R Voice" — de hardware is inmiddels **M5Stack Atom S3 Lite** (board `esp32-s3-devkitc-1`).
+
+## Wijzigingen
+
+### 1. Firmware: pullup verwijderen + schakellogica inverteren
+
+Beide firmwares hebben identiek patroon, 2 regels per file:
+
+| Bestand | Locatie | Huidig | Nieuw |
+|---------|---------|--------|-------|
+| `src/main.cpp` | `pinMode(TOUCH1/2_PIN, ...)` | `INPUT_PULLUP` | `INPUT` |
+| `src/main.cpp` | `digitalRead(TOUCH1/2_PIN) == LOW` | `== LOW` | `== HIGH` |
+| `src/client.cpp` | `pinMode(TOUCH1/2_PIN, ...)` | `INPUT_PULLUP` | `INPUT` |
+| `src/client.cpp` | `digitalRead(TOUCH1/2_PIN) == LOW` | `== LOW` | `== HIGH` |
+
+**Rationale:** JR223B met pullup → normaal HIGH, aanraking trekt naar LOW. HS-S43A → actieve digitale output, aanraking = HIGH.
+
+Debounce (`DEBOUNCE_MS=50`) blijft ongewijzigd — HS-S43A is stabieler, bestaande debounce is ruim voldoende.
+
+### 2. Documentatie: S3R → S3 Lite
+
+Alle 27 verwijzingen naar "S3R", "AtomS3R", "Atom VoiceS3R", "Atom S3R Voice", "m5stack-atoms3r" in 8 bestanden:
+
+| Bestand | Aanpassing |
+|---------|------------|
+| `AGENTS.md` | Board: S3R Voice → S3 Lite. Flash commando pad: `m5stack-atoms3r` → `s3lite-server`. Touch: G8+pullup → G8, G6+pullup → G6 |
+| `README.md` | Board spec, serial banner, pin-doc: S3R → S3 Lite |
+| `.forgejo/workflows/ci.yml` | Build output pad: `m5stack-atoms3r` → `s3lite-server` |
+| `tools/copy_firmware.sh` | Build output pad: `m5stack-atoms3r` → `s3lite-server` |
+| `docs/superpowers/specs/2026-07-28-esp32-pico-d4-port-design.md` | Contextuele S3R verwijzingen — doel/resultaat beschrijvingen intact laten, alleen boardnaam corrigeren |
+| `docs/superpowers/plans/2025-07-31-sylda-nimble-hmac-plan.md` | 1 match: comment over S3R pinmap |
+| `docs/superpowers/plans/2026-07-30-ble-ota.md` | Build output pad: `m5stack-atoms3r` → `s3lite-server` |
+| `docs/superpowers/plans/2025-07-28-esp32-pico-d4-port.md` | Meerdere referenties naar S3R — historische context behouden, boardnaam corrigeren |

+### 3. Risico's
+
+- **Geen rollback zonder herflashen** — na flashen werkt JR223B niet meer.
+- **Beide devices flashen** — server + client(s) moeten gesynchroniseerd zijn.
+- **Geen runtime-switch** tussen sensortypes — YAGNI.
+
+## Niet in scope
+
+- Geen wijzigingen aan BLE-protocol, HMAC, OTA, of Android app.
+- Geen configuratie-mechanisme voor sensortype.
